In a room 12'-4" by 13-9" with 8'-0" high ceiling, there is one door 3x7' and two windows 4' square. Answer the following questions. Assume there is no waste in materials, and round off
your answers
A. How much wall surfacee in square feet is there to paint?
B. What is the floor area?
C. How many gallons of paint will be required to cover the walls with 2 coats of paint if each
gallon covers 200 square feet of surface?
D. How many lineal feet of cove base floor trim will be required?

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

step-by-step explanation:

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
